Abstract:

Field experiments were conducted to evaluate quantitative and qualitative characteristics of yield in dryland wheat cultivars under supplemental irrigation conditions. In these split plots randomized complete block design experiments were used, the main plots consisted of five irrigation treatments while sub plots consisted of three dryland wheat cultivars. Results showed that supplemental irrigation increased wheat cultivars yield compared to control (no irrigation). Sardari cultivar produced the highest yield with two times supplemental irrigations at planting and flowering stages. The highest grain N content was found in Azer₂ cultivar under no irrigation conditions. In general, application of one time supplemental irrigation at flowering stage significantly increased grain yield in Sardari cultivar.
